wa alaikum Hello
brother this is a normal thing when you are using non solar gadgets with the solar gadgets ,
the main thing to understand is that APC shuts off its charging on 27 point something volts and consider the battery FULL CHARGED state , but when in any case battery gets MORE charged beyond 27 to 28 volts or more then APC beeps a warning that your batteries are getting overcharged !!!! thats nothing to worry about , i have faced this same thing numerous times .
i dont know what charge controller u r using , The cutoff volts of your c/c is 29 volts that is pretty good for a slow charging option (to save batteries life) , u can check that even touching 29 volts your batteries are not HOT !! (if they are not in USE and only in charging state) this is all bcz of your c/c that monitor the charging process keenly .
so not to worry about . Simply restart the APC . and yes u can change the cutoff volts settings of your APC to 29 volts but i would not advise you for this . bcz the charging process of APC and C/C is different and it is wise NOT to use 2 chargers on same batteries same time .
